Procedure

2-Amino-6-methoxy-pyrazine (1.00 g, 8 mmol) was dissolved in a mix of 1:2 THF:MeCN (30 mL), cooled to 0° C., and treated with pyridine (0.664 g, 8.3 mmol) followed by the dropwise addition of phenylchloroformate (1.3 g, 8.3 mmol) in THF (10 mL). After stirring for 18 h, the resulting white solid was collected by filtration (1.3 g, 68%) and was used without further purification.
